Medical imaging: Positron emission tomography (PET)
Positron emission tomography (PET) is a technique for measuring the biodistribution of a drug labeled with a trace amount of radionuclide and is widely used in medical fields such as for cancer diagnosis. It is characterized by high sensitivity and quantitativeness that can detect extremely small molecules in the deep parts of the body. In this article, the mechanism of the PET device and some points to keep in mind to make use of these characteristics will be explained.
